Question

6 sin 90°-3 cos 180°

Answer 1

6 sin 90°-3 cos 180°= 6 * 1 - 3 * (-1) = 6 - (-3) = 6+ 3= 9

Answer 2

To solve the expression 6 sin 90° - 3 cos 180°, let's first evaluate each trigonometric term separately:

sin 90° = 1 cos 180° = -1

Now substitute the values back into the expression:

6 sin 90° - 3 cos 180° = 6(1) - 3(-1) = 6 - (-3) = 6 + 3 = 9

Therefore, 6 sin 90° - 3 cos 180° equals 9.
